Merge patch series "ns: rework reference counting"
Christian Brauner <brauner@kernel.org> says:
Stop open accesses to the reference counts and cargo-culting the same
code in all namespace. Use a set of dedicated helpers and make the
actual count private.
* patches from https://lore.kernel.org/20250918-work-namespace-ns_ref-v1-0-1b0a98ee041e@kernel.org:
ns: rename to __ns_ref
nsfs: port to ns_ref_*() helpers
net: port to ns_ref_*() helpers
uts: port to ns_ref_*() helpers
ipv4: use check_net()
net: use check_net()
net-sysfs: use check_net()
user: port to ns_ref_*() helpers
time: port to ns_ref_*() helpers
pid: port to ns_ref_*() helpers
ipc: port to ns_ref_*() helpers
cgroup: port to ns_ref_*() helpers
mnt: port to ns_ref_*() helpers
ns: add reference count helpers
